Before you make any adjustments, read the chair manufacturer’s instructions on how to properly adjust it. Learn all about the chair's adjustable features.
Sit in the chair with your feet on the ground. You want to achieve a chair height that allows you to sit all the way back with your feet on the floor.
Push the height adjustment lever backward to move the chair up and down. It is typically on the right side of the chair.
Stand up off the chair slightly to reduce the pressure of the chair as you push the lever. This will raise the chair height.
When you have found the correct position, push the lever forward to lock it into position.
